What You'll Do As a Senior Propulsion Development Engineer at Inversion, you will design, build, and test liquid and gas propulsion systems for our next-generation Arc hypersonic reentry vehicle, with an emphasis on Attitude Control System (ACS) thrusters, fluid feed systems, and propulsion components. You will own the mechanical design and analysis of fluid networks, manage hardware fabrication, author test plans, procedures, and reports, and lead hot-fire test campaigns. You will work cross-functionally with structures, avionics, software, and test teams to physically integrate propulsion hardware into the vehicle and verify system performance against mission requirements.
Required Qualifications - Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.
- Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or equivalent technical experience.
- Typically 5+ years of hands-on experience in the design, build, and testing of high-pressure fluid or rocket/spacecraft propulsion systems.
- Expertise using CAD software (Siemens NX or equivalent) for mechanical packaging and fluid line routing.
- Strong foundation in fluid mechanics, thermodynamics, structural mechanics, and materials compatibility.
- Experience working hands-on with high-pressure fluid components, plumbing (tubing, fittings, manifold blocks), and pneumatic systems.
- Demonstrated excellent verbal and written communication skills with the ability to write detailed test and hazard procedures.
Desired Qualifications - Direct experience with spacecraft Attitude Control Systems (ACS), cold-gas, warm-gas, or monopropellant/bipropellant thruster systems.
- Familiarity with high-pressure gas system operations, nitrogen/helium systems, and safety-critical hazard controls.
- Experience with ANSYS Mechanical or equivalent FEA software.
- Experience using Python, MATLAB, or GFSSP for fluid system analysis.
- Prior experience performing acceptance and qualification testing of propulsion components or systems in accordance with standards such as SMC-S-016, GSFC-STD-7000A.
- Prior experience in a fast-paced aerospace startup, collegiate rocket/propulsion team, or small independent hardware team.
